The ORNL ECR multicharged ion source

Spark discharge coupled laser multicharged ion source.

A spark discharge is coupled to a laser multicharged ion source to enhance ion generation. The laser plasma triggers a spark discharge with electrodes located in front of the ablated target. For an aluminum target, the spark discharge results in significant enhancement in the generation of multicharged ions along with higher charge states than observed with the laser source alone. When a Nd:YAG...

Status of the Ins Ecr Ion Source

An ECR source for the INS SF cyclotron has been constructed. Test operation is being performed in a single stage configuration in order to study the behavior of the source, before it is installed. Some results are presented.

Venus: the next Generation Ecr Ion Source

The construction of VENUS, an Electron Cyclotron Resonance ion source designed to operate at 28 GHz, is nearing completion. Tests with the superconducting magnet assembly produced axial magnetic field strengths of 4 T at injection and 3 T at extraction and a sextupole field of 2 T at the plasma wall. These fields are sufficient for optimum operation at 28 GHz. We expect a shift to higher charge...

Ion Beam Measurements at the Superconducting ECR Ion Source SECRAL

Use of an Ecr Ion Source for Mass Spectrometry

At ANSTO we have developed an Electron Cyclotron Resonance (ECR) ion source to investigate new concepts for mass spectrometers designed to measure isotopic ratios of elements such as carbon, nitrogen and oxygen. The low pressure ECR plasma presents particular challenges when used for mass spectrometry. The elements we are interested in measuring are typically present as residual gas in vacuum s...
